Slags, chavs, idiots behave in a certain way. Do you want to copy them?
How do you expect a kid who's grown up in a NORMAL, STATE SCHOOL all their lives to NOT pick up this stuff. Just Becuase they speak like that it doesn't make them what you say they are. There are quite a few decent brothers who speak like that, but they know how to speak to their elders...They also know where to speak properly.......Even I speak like that among my friends. What are you going to do about that? It just shows that we're not so proud of our status (Being an upper class, stuck up, spoilt fool)
Stop being such a stuck up person. I take it you're extremely rich and spoilt. Go to chess clubs after school, go to a school like Dulwich college and pay over £25,000 every term. Not everybody has that sort of money.
